Recirculating roller screws

SKF recirculating roller screws can simplify a complete transmission and improve its rigidity. They are often used in applications of advancing technology where reliable optimum performance is essential.
SKF recirculating roller screws are available with a large range of diameters and leads. Their great mechanical advantage minimizes input torque and increases application resolution and performance.

Features and benefits

Shaft length up to 8 000 mm (please consult SKF for longer screws)

Standard lead precision G5 (ep=25µm/300mm) to G1 (ep=6µm/300mm)

Optional stainless steel material

Optional surface treatment for shaft and nut

Optional wipers

Optional support bearings

Very fine lead down to 1,0 mm, while providing a high load carrying capacity and high axial stiffness

Fine resolution for high positioning accuracy with high repeatability

High axial stiffness, further increased with preloaded versions

Easy nut disassembly from the shaft if necessary

Limited torque thanks to small lead and high efficiency

No miniature parts to improve robustness and reliability

Many strong contact points provide heavy load capacity and long service life
